TILE-MAKING MACHINE.

Specification of Letters Patent.

Patented (lot. 12, 1909.

Application filed May 3, 1908. Serial No. 493,643.

To all whom it may concern: l

lie it known that I. Woman J. Mc- (n.vcunx. a citizen of the United States, residing at Paullina, county of UBrien, State l of Iowa, have invented certain new and usel ful Improvements in Tile- Making Machines: and I do hereby declare the following to be a full, clear. and exact description of the invention. such as will enable others skilled in the art to which it. appertains to This invention relates to improvements in tile making machines. and particularly to means for forming the same more compactly. and has for an object the arrangement of a plurality of projections or enlargcnients for firmly packing the cement or material making the tile against the walls of the mold.

A further object of the invention is the arrangement of a former divided into a plurality of parts one. of which is. arranged to pack the cement against the mold, and the other is designed to smooth and finish the interior of the tile;

Another object in view is the arrangement of a packer head or former having a smooth iug member arranged with a projection for receiving a packil'ig shell. and means for holding the various parts together so as to cause the packing shell to pack the cement previous to the engagement of the same by the smoothing member.

A till further object of the invention is the arrangenu-nt of a packer head or former having a removable shell construction that is formed with parkingsurfaces. the shell being arranged to lie held between the smoothing member and the retaining member. the. retaining member being bevelml for permitting cement to be easily engaged by the packing sin-fates. \Yith these and other objects in view the invention comprises certain novel constructions. combinations and arrangement of parts as will. be hereinafter more fully described and claimed.

In the accompanying drawings: Fightin is a longitudinal vertical section through a mold showing the former in position. Fig. 2 is a side elevation of the. former removed. Fig. 3 is a section through Fig. 4 on line; Elproximately on line 4 4. Fig. 5 is a top: plan. view of a smmthing member. Fig. 6 l

Fig. -lis a section through Fig. 2 ap fcicnt. In the pl'esent invention it is among the objects of the invention to form a packing shell or member that may be quickly rcncwed and one that will effectually pack the tile or cement. The packing shell is easily removed and replaced at comparatively small cost without renewing any of the sur rounding parts which is of great advantage in savingcnpense and in causing only a comparatively short time to be lost in repairing the former.

In order that. the invention may be more clearly understood'an embodiment of the same is shown in the accompanying drawings in which"- 1 indicates a mold of any desired kind havinothe usual well 2. The former is designer to-be. placed in well 2 or below mold 1 and the cement or other material of which the tile is to be made is placed in the mold and the former rotated and at the. same time moved upward. This will cause the former to pack the cement against the mold 1 as the former rises. The well 2 of course may be dispensed with and any desired support. provided for mold 1 that will permit the former to pass freely dowmvard below the bottom of the mold.

in constructing the former the. same is provided with a smoothing member or part 3 which formed in a cylindrical shape and of the same diameter as the interior of the The smoothing member fl ,thuaidedaperture-tor-re bore of the tile. is provided w th ceiving if'tin'eaded pin t which is provided with shoulders 5 for clamping a guiding and upper member or part (3 in position.

The smoothing member 3 is formed with a ilurality of upstanding lugs 7 arranged to tit into a packing shell or mcmbm' H. Th I05 upper memberor guide 6 is also formed with a plurality of lugs 9 of the same shape and number as lugs T so as to lit. in the same packing shell 8. The packing shell S is tt-iimcd with a plurality of projections or surfaces 1.0 which are parti-cylindrical and of such afsize as to have the outer part thereogfat one point come flush oreven with the surface or periphery of-smoothing member 3 as clearly shown in Fig. 4. In the drawings three lugs 7 and 9 have been :shown With'a shell 8 to correspond therewith, but it will be evident that two may be used or four or more as occasion may require. tlhe lugs 9 and also the lugs 7 project into shell 8 and preferably are made to meet substantially midway thereof which firmly holds the shell in osition, and permits power to be conveyed 'rom shaft l to the shell, as well as to smoothing member 3.

In 0 eration the former is passed down throng mold 1 until the upper edge of smoothing member 3 is level with the bottom of the mold, and then cement or other material is poured into the mold and the former rotated and moved upward at the same time. The rotation of the former will cause the parti-cylindrical portion 10 of shell 8 to pack the cement against the side of the mold evenly and comparatively smoothly. As the former moves upward the smoothing member 3 follows the packing shell 8 and completes the smoothing of the interior of the tile. Member 6 is formed as a continuation of the shell 8'but is gradually reduced untilthe same comes almost flush with the periphery. of shaft 4. 'For instance, in the former shown in the drawing shell 8 has three parti-cylindrical members,

and part 6 has three parti-cylindrical lugs merging into aeylindrical member at the top. By this structure the cement is guided not only to its proper place between the i ormer and the mold, but also between the respective parti-cyl-indrical portions'or members 10 from wh1ch it is forced against the mold or against other cement .for com pacting or pressin the same.

@ne of the important features of the invention is the removability of the various I parts for renewah'repair or inspection. ll i shell 8 should become worn to an undesirable degree the same could be removed and a new one placed in position without injuring" or without discarding the remaining parts. Parts Sand 6 couldalso berenewed in alike manner without renewing the remainin parts so that in practical operation on y new parts are necessary to be supplied that wear out and as shell 8 creates more friction than any of the remaining parts the same wears more rapidly even though made out of hard material. The material in shell 8 is comparatively small andthe expense of renewal of the same is 'small in comparison with the expense of the renewal of a complete former.

It will be observed that one of the chief advantages of this packer head is that the packing shell 8 is soarrangcd that when the sides of projections 10 thereon are worn by use, the part 8 may be reversed. end for 0nd, thus bringing the opposite sides ol projow tions 10 into packing position to recoivolho wear of packing thus doubling the life of said packing shell.

What I claim is:

. In a former for tile forming machines, a packing shell formed with a plurality of n11'ti'-cylindrical members, a smoothing member arrangedto co-act withsaid shell and formed with projections extending into said shell. and a guiding member formed with projections extending into said shell for holding the same properly in position, and means for binding said guiding mcm ber, shell, and smoothing member together for conveying power thereto.

In testimony whereof I ailix my signature in presence of two witnesses.
